TRUCK-BOLSTER.

larly to truss holsters built o f-rolled steel, and to thev mode of attaching the ende-frc the thrust and tension members. The objects ofmjl invention are, to make a safe and strong lap connection oi the tension and thrust members; to make an improved bearing seat at the end of the bolster; to better secure 'theharing block and the end of the tension member in place, and to generally improve the construction of truck holsters. The

invention is shown in a preferred form in the accom! panying drawing, wherein- Figure -l is a partial side elevation and a partial longitudinal section through the end of mv improved holster;

Figure 2 is a top plan view of one end, and Figure 3 is a plan of the compression member alone;

Figure 4 is an enlarged cross section taken on the line (4).in Figure l, and l l Figure 5.is a plan view of ing 'of the tension member.

In holsters ofthe typeof construction herein shown, which consist essentially 0i a truss iu which the compression member ismade of a channel or I-beam, it is very important to make such connection between the thrust member and the ends of the tension member as to prevent the marring or wear ofthe latter; it is also Y important to arrange the parts andthe bearing block so that the center of the bearing may come directly under thepoint of attachmentof the tension member to the thrust member. To accomplish this and the other purposes specified, I preferably make the construction by forming the compression member 6 of'channel iron with depending flanges 7, and the tension member is the flat i bar 8 which has bent over ends 8 engaging the thrust member, both resting on a bearing block 1 0 which is attached to the tension member and also supports an outer projecting end Slot the thrust beam 6. The two memthe cross plate for the bearbers of the truss may be separated and strengthened at lapped back upon the 'top of the web between the two flanges 7. lt rests uponthe cross plate 13 which lies upon the top ofthe beam 6, extending laterally over the flanges of the beam and has a depending rounded portion 13 extending into the slot l2 to make a larger and better bearing for the memberA 8, The bearing block 1 0 is provided with upwardly projecting flanges which embrace the entire end of the bolster on the outside of the anges 7 of member 6, and receives and transfers the upward pressure on the bearing against both the tension member 8 and the extended end 9 of the thrust beam 60 beyond the slot i2, as clearly shown in Figures l and 2.. The bolster may be provided with any desired form of strut 14, and the end 8 of the tension member is held down by rivets l5 or in any manner desired. It is also desirable to rivet the cross block 13 yas shown in Figure l. 6 5 By this construction the center oi the endbearingis brought directly under the point of attachment of the tension and thrust members, and the cross plate 13 rests both on the inner edge of the opening in the web, and

' by its outer ends rests on the anges ofthe channel 0r 70 I-beam which forms the thrust member. The block l0 securely houses all the parts, and it will be seen that the construction is very compact and there is no strain upon the rivets in taking up the stresses of the truss. Other advantages of the device will readily. occur to those 75 familiar Witlrthe art.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is the following:

1. A truck bolster comprising in combination, a compression member, a. tension member having one end folded around the same, and a bearing member therefor having its center substantially in line with the fold .of said-tension member.

2. A truck holster comprising in combination a flanged compressionmember, afiat tension member having one end folded around `the same, and a bearing member therefor having its center substantially in line with thefoldoff/sf'lid tension member.

3. A truck bolster comprising in combinations compres- 9() sion member provided -with a slot spaced from the end, va tension member passing through said slot and folded back upon the compression member and a hearing' member'therefor having its center substantially in line with the fold of said tension member.

4. A truckboister comprising in combination a. compressioinmember provided with a slotfa tension member passing through said slot and folded back upon the compression member, together with a bearing member embracing the end of the compression member and having its center 4substantially in linewlth the fold of the tension member.

5.- A truck .bolster comprising in combination n iianged com pressionmember provided with a s io't in its web portion, a tension member lapped in said slot and a bearing member having its center substantially in line with said iupprd portion und provided with a flange embracing the end ot' the compression member ouiside its flanges.
